Specification forming part of Letters Patent No. 166,265, dated Ailgust 3, 1875; application filed July 6, 1875.

To all whom itlimay concern:

Be it known that I, TAYLOR E. DANIELS, of Detroit, in the county of Wayne and State of l\lichigan,"have invented certain Improvements in Artificial Marble, of which the fol- IOSll] pound; water ten gallonssugar, three pounds; alum-water, one gallon; cement, a sufiicient quan i-y. i

I first cut the linseed-oil with alcghol, and then melt together the bees-wax, resin, and borax, and, after bringing the oil to a white heat, add them thereto. I next heat the water to the boiling-point, add the sugar thereto,

and then boil for five minutes, after which the ingredients first combined are added. to the water, and'the entire mass boiled for fifteen. minutes, after which the alum-wateris added,-

and the boiling continued half an hour longer. The compound, while hot, is then filtered through charcoal, after which hot water-is added until the compound is increase in quantity to about forty gallons, when it is permitted to cool. vThe cement is then provided in a quantity sufiicient for the special occasion, and the fluid added thereto until the mass is reduced to a plastic condition; It is then molded into the required form, and permitted to dry and harden, the drying operation being facilitated, if desired, by the use of a dry kiln or oven.

When it is desired the surface of the molded objects may be hardened and finished by the application of a solution of one gallon of silicate of soda, boiled in ten gallons of water.

The marble may be colored and grained by the application of suitable materials to its surface, or by incorporating them in the mass before or during the operation of molding. One convenient manner of imitating the natural veins in the material is to place strings of the colored material in the mold, and then fill in and around them with the main body of material. Where very delicate lines are desirable the fine threads of colored material are laid upon the surface of paper which is placed in the bottom of the mold to receivejiie body of material. After the article is hardened and removed from the mold the paper is moistened and drawn on, leavin g the fine colored threads in the surface of the molded object.

Having described my invention, what I claim is- A composition for artificial stone consisting of bees-wax, bora rosin, alum, sugar, linseedoil, cement, and water, in substantially the proportions specified,.with or without the application of silicate of soda.
